Slow Motion Photography: Illustrating Quadratics

Many years ago I came across an article that had an image of chronophotography of a water skier. Chronophotogrpahy places time lapse shoots on the same photo to show its motion or trajectory. I got really excited as it was a great way to illustrate motion in my class - and give a visual aid for students in my class. A few years ago, I made a set of two sheets for Quadratic Modeling using these photos as inspiration. I built equations and questions to suit each real life photo. It was a lot of work at the time, but the worksheets have been so effective I have used them every year in my class.
